MANUFACTU RE OF BLOOM S.

SPECIFICATION forming part of Letters Patent No. 441,474, dated November 25, 1890.

Application filed September 29, 1890. Serial No. 366,515. (No model.

T0 all whom zl t may concern:

Be it known that we, WILLIAM EYNON and WILLIAM SEAMAN, both citizens of the United States, and residents of Vilrnington, New Castle county, Delaware, have invented certain Improvements in the Manufacture of Piles or Billets for Rolling-Mills, of which the following is a specification.

The object of our invention is to provide for the economical manufacture of pilcs or billets for being subsequently reduced into bars or other forms by a rolling-mill, and this object we attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a muck or puddle bar representing the first stage in the preparation of the improved pile or billet. Figs. 2 and 3 are perspective views representing different embodimen ts of the second stage of the process, and Fig. 4 is a perspective view of the completed pile or billet.

It is now the usual practice in rolling-mills to cut into short pieces the bar delivered by the muak or puddle rolls, and then to pile and confine these pieces in the form of a rectangular block, which is charged into the fur nace and reheated prior to being subjected to the action of the finishing-rolls, whereby the manufature of the bar or other form of rolled iron is effected. The cutting and piling of the bar necessarily imply either the complete or partial cooling of the same and the consequent loss due to the necessity of subsequently reheating the pile.

In carrying out our invention, therefore, we take the muck or puddle bar Asuch, for instance, as is shown in Fig. land either coil the same, as shown in Fig, 2, or fold it, as

shown in Fig. 3, so as to form a tube or block approximating in size to the required size of the finished pile. The coiled or folded bar is then subjected to the action of a steam-hammer, a hydraulic press, or other equivalent pressing or squeezing device, whereby it is solidified and compacted into the form of a homogeneous slab or billet B, as shown, f0r instance, in Fig. 4. These operations can be performed without the loss of a large per centage of heat by the bar. Hence when the billet is charged into the reheating-furnace it can in a short time be brought up to the proper heat for rerolling, thus saving both time and expense not only in the preparation of the pile or billet, but also in the reheating of the same.

We are aware that rolled bars have been coiled or folded to form a finished article of manufacture, and hence do not broadly claim such coiling or folding of a finished bar; but

We claim as our invention and desire to secure by Letters Patent- The mode herein described of preparing a pile or billet for subsequent conversion, said mode consisting in coiling or folding the muck or puddle bar while it is hot into billet form, and then while still hot hammering or compressing said coiled or folded bar into a solid billet, substantially as specified.

In testimony whereof we have signed our names to this speoification in the presence of two subscribing witnesses.

WM. EYNON. WM. SEAMAN.
